Abstract
According to a liquid crystal panel 10 provided by the present invention, in the vicinity of an inner surface of a sealing portion 16 located on a peripheral portion 10a between a pair of substrates 11 and 12 in order to hold a liquid crystal layer 13 between the substrates 11 and 12, barrier portions 49 and 59 formed of a material for forming alignment films 48 and 58 are formed to be thicker than the alignment films 48 and 58.
Claims7
A liquid crystal panel, comprising:
- a pair of substrates facing each other;
- a liquid crystal layer located between the pair of substrates;
- and
- a sealing portion located on a peripheral portion between the substrates so as to surround the liquid crystal layer in order to hold the liquid crystal layer between the pair of substrates;
- wherein:
- an alignment film for aligning liquid crystal molecules in the liquid crystal layer is formed on a surface of at least one of the pair of substrates, the surface facing the liquid crystal layer;
- a barrier portion, formed of an alignment film material for forming the alignment film, for trapping moisture is formed to be thicker than the alignment film, the barrier portion being formed in the vicinity of an inner surface of the sealing portion;
- a groove is formed along the inner surface of the sealing portion on the surface of the substrate which faces the liquid crystal layer;
- and
- the barrier portion is formed by the alignment film material being accumulated in the groove.
